Pre-shot RAPTOR-FBT simulations of TCV ohmic and NBI-heated discharges

Associated publication [1] C.E. Contré et al 2026 Nucl. Fusion 66 086053 General description This dataset contains predictive simulations of TCV tokamak discharges performed using the RAPTOR [2] fast radial transport code. Transport fluxes are estimated with a gradient-based transport model [3], newly extended to model transitions from Positive (PT) to Negative Triangularity confinement and include ion temperature modeling [1]. Simulations were run predictively from the pulse schedule, using only the line-averaged density from experiment (model E1 in [1]). Equilibrium is computed using FBT [4], an inverse free-boundary equilibrium code of the MEQ suite. Both RAPTOR and FBT are coded in Matlab and versioned with Git. The 211 shots were selected based on data availability and heating scheme (fully ohmic or with NBI) in the range 82000-82999, which corresponds to a period of approximately 2 months of TCV experiments. More details about the methodology used can be found in the publication of reference [1]. Format Results are sampled down to a 2ms time step and stored in the IMAS-3.0 IDS (hdf5) format [5,6] for easy share among the fusion community. This format follows the FAIR principles.
